50 years since the first Pride in the UK! What happened: Their relationship was hidden for a while, partly because Marceline and Bubblegum broke up many years ago.
They got back together with a last-minute series finale kiss, but it only confirmed what the writers had been hinting at for years. Why it was great: I count this as a good one because the relationship was as heavily implied as the writers were allowed to make it, and it makes sense for exes to avoid talking about their past.
We also got a whole wonderful episode about their relationship in Adventure Time: Distant Lands.What happened: There were zero hints to their relationship or queerness in the show, so it was surprising for many when they held hands at the end.
Their story was continued in the comics, where the relationship was confirmed.Why it was disappointing: As much as people loved seeing Korra and Asami get together, their romantic relationship kind of came out of nowhere, and we never got any build-up to it.
